Cell Test
| Question | Answer |
|---|---|
| Identify the transport method used to get solids into some animal cells. | Endocytosis |
| How is diffusion different from other transport methods? | Spontaneous tendency of a substance to move down its concentration gradient from a more concentrated area to a less concentrated area. It happens naturally. |
| Membrane proteins, also called carrier molecules, are required for which types of transport? | Facilitated diffusion, Protein pump |
| What type of molecules move through the cell membrane the fastest? | small non-polar. EX:o2 and co2 |
| What is the function of exocytosis? | To move bulky material out of the cell whether its nutrients go elsewhere or to rid waste. |
| How do daughter cells at the end of mitosis and cytokinesis compare with their parent cell when it was in G1 of the cell cycle? | The daughter cells have the same number of chromosomes and the same amount of DNA. |
| What is the shortest part of the cell cycle? | Mitosis |
| When does chromosome replication occur? | Synthesis/S phase |
| Prophase | The chromatin is condensing. The nucleolus is still present but will begin to disappear. The mitotic spindle is starting to form and the nucleolus and nucleus are still intact. |
| Mataphase | The spindle is complete and the chromosomes, attached to the microtubules at there kinetochores are all at the metaphase plate. |
| Anaphase | The chromatids of each chromosome have separated, and the daughter chromosomes are moving to the poles of the cell as their kinetochore microtubules shorten. |
| Telophase | Daughter nuclei are forming while cytokinesis has started. The cell plate will divide the cytoplasm in two, growing toward the perimeter of the parent cell. |
| Cytokinesis | The division of the cytoplasm to form two separate daughter cells immediately after mitosis occurs in plant cells. |
| If a cell has 46 chromatids at the start of mitosis, how many chromosomes are in the daughter cells? | Each daughter cell has 23 chromosomes. |
| Nucleus | Contains genetic material |
| Chromatin | Stores genetic material of cell |
| Lysosome | used to degrade macromolecules |
| Mitochondria | Sit of cellular respiration |
| Flagella | Used for Locomotion |
| Smooth Endoplasmic Reticulum | Lipid synthesis detoxification, a site of synthesis secretory proteins |
| Rough Endoplasmic Reticulum | Proteins synthesized. Ribosomes collect on this site for transport throughout the cell. |
| Golgi Apparatus | Modification of products from endoplasmic reticulum. |
| Cytoplasm | Holds cell together. |
| Ribosome | The site of protein synthesis |
| Nucleolus | Produces ribosomes. |
| Cell Wall | Acts as a protective barrier to the uncontrolled flow of water. |
| Vacuole | Used to degrade macromolecules |
| Chloroplast | Site of plant photosynthesis. |
